I bought the set and will be starting a rotation with them as soon as I finish up my current one. I am very excited to get started and,from the previews I have done, really like what I see. I do plan on following one of the rotations (which I have rarely ever done until recently but these rotations look doable to me).
I had ended up buying 5 of the workouts from Mary individually and then decided to return them and just buy the entire set, made more sense to do it that way and I am happy I did.
I will probably end up doing that with her new series, as well, since I know for sure I want at least four of the new ones.
